Palacio is the stately west end of the old city: the Palacio Real's 3,000 rooms, the Almudena cathedral, the Teatro Real opera house and the manicured Sabatini and Campo del Moro gardens, all draped along the escarpment where Madrid began as a 9th-century Moorish fort. For a barrio wrapped around the city's biggest monument it stays strangely calm — tour groups drain away at closing time and the evenings belong to locals walking dogs in the Plaza de Oriente.
It's the connoisseur's central base: five minutes from Sol, ten from Gran Vía, with none of their noise. Hotels cluster around Ópera and Calle del Arenal, from opera-goers' classics to small design hotels in 18th-century buildings.
Royal escarpment sunset walk — 2.5 km · 1 h. Plaza de Oriente → Sabatini gardens → down around the Campo del Moro railings → Cuesta de la Vega → Almudena viewpoint → Las Vistillas for sunset over the Casa de Campo. The city's western cliff edge, golden hour.
Ópera station (L2, L5, plus the R shuttle to Príncipe Pío) is the hub; Príncipe Pío itself adds Cercanías and buses to the sierra's western towns. Sol is 5 minutes' walk, Gran Vía 10. Airport ~40 minutes via L2 + L8.
Around the Plaza de Oriente and Calle de Vergara for the full royal-quarter effect; Calle del Arenal for the direct line to Sol; toward Plaza de España for newer stock and the gardens. Evenings are quiet everywhere here — this is the centre's best barrio for actual sleep.
